SPECIFICATION, forming part of Letters Iatent No.760, 5"76, ,dated May 24, 1904, i Q Application filed anuaryZ, 1903. Serial No. 137,488. '(No inodelal l i To all whom it may concern: I I Be it known that I, OHRISTAIN SoNKE, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain newand ,use.

ful Improvements in Devices for Turning the Wheels of Band-Saws; and I do hereby declare the following to be a full, clear, and eX; act description of the invention, such as'will enable others skilledin the art to which it appertains to make and use the same.

' My invention relates to improvements in de vices for turning the wheelsof band-saws in the process of construction or. cleaning or returning the same after use; and its object is to provide a device that can be readily attached to. the band-saw frame and brought in proper relation to operate upon the surface of certain new and useful features. hereinafter.

the Wheels that engage the saw while the same are in motion and to provide the device with more-fully described, and particularly pointed out in the claims; 7

My device consists, essentially,of-a suitable tool to engage and cut away or to clean the rim of the wheel, a clamp adapted to engagev beinghad to the accompanyingdrawingsQin which s Figure 1 is a plan view of a deviceembodying my=invention; Fig.2, afront elevation of the same; Fig. 3, an end elevation of the lefthand portion of the-same;lFig.- 4, a vertical section on the line 4 4: of Fig. '1, and Fig. 5 the slidably engages the .back of the tool and is of the same on 'the line 5-5 of Fig; 1. Like letters refer tolike parts in all figures.

' Arepresents-aportion oft a; frame of a band-saw machine, B, a portionof one of the wheelsof the said machine, said wheel having a surface of leather adapted to engage and operate the band-saw; C, a suitable clamp adapt-' and adjustably hold the bar E, to which bar is attached a bed-plate F, on which plate is I mounted a carriage Gr, adjustable toward and f from the wheel B by means of a. screwR, journaled in suitable bearings F on the bedplate and extending through-and engaging the screw-threaded lug G on the carriage. An-

other lug G on the carriage slidably engages the screw at a distance from the lug G, whereby thescrew and lugs serve to both adjust and guide the carriage on the bed-plate without the use of the usual ways to guide the carriage. Longitudinally slidable on this carriage is a. suitable tool L, consisting of a thin plate of steel, having the middle portion ofits forward 'edgeserrated or toothed and projecti ing over the edge of the carriage to engage and cut away or clean the surface of'the wheel B, which surface consists usuallyofa layer of leather or other suitable material. i The middle portion of this tool is'parallel Withits length or line' of movement and adapted to engage the surface ofthe wheel parallel with inclined,-as at M, to-bevel off the edgesof the its axis. The endsof thistool are widerand wheel, and b( tween these portions arerecesses a L, which do not contact the wheel, whereby the end portions and the middle portion of the t toolare independentlyoperative;.at pleasure I without readjusting the carriage. This tool.

rests-upon. the carriage and .slideslongitudi nally thereon. j i N is a rack-bar extending along the backof [the tool' and engaged by a P nion Oto move the tool longitudinally on the carriage. Said pinion ismounted on a shaft 1?,journaled in suitable-bearings on the carriage and provided withaicrank .Q. F To adjust the tool on the carriage, a bar J in these clamps are adjustable blocks 1, attached to'the bar J, and extending above the rack-bar N, and thence downward and engaging the top and front of the bar, whereby the rear of the tool is held down upon the carriage and permitted to slide longitudinally thereon. The tool can thus by means of the screw K be adjusted to projeetslightly beyond the front of the carriage and readjusted as it is worn away, and by means of the screw R the carriage, together with the tool, can be moved toward the wheel B to engage and properly cut or clean the same, and by turning the crank Q the rack and pinion will move the tool longitudinally to properly operate the same, and at the same time the clamps and blocks prevent any viabration of the tool.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of a carriage, means for supporting the same near a band-saw wheel, a tool consisting of an elongated plate having a serrated edge to engage the wheel and slidable on the carriage, a rack on the plate, a pinion engaging the rack, and means for retating the pinion.

2. The combination of a carriage, means for supporting and adjusting the same relative to aband-saw wheel, a tool consisting of a plate longitudinally movable on the carriage and having a serrated edge on its middle portion adapted to engage the wheel and also having inclined ends, and recesses between the ends and middle portion, and means for moving the tool longitudinally on the carriage.

3. The combination ofa carriage, means for supporting and adjusting the carriage relative to a band-saw wheel, a plate slidable on the carriage and having a serrated edge to engage the wheel, a rack on the plate, clamps on the carriage and engaging the plate near the front thereof, a pinion engaging the rack, and means for rotating the pinion.
